The Greek PhD acknowledges that atmospheric CO2 has risen sharply in just a few years...he knows

that CO2 is a Greenhouse Gas...he failed to notice that the above average increase is due to Human burning of Fossil Fuels...How do we know that?...because FFs were formed tens of millions of years ago (50-350Myrs), and the half-life of C-14 is 5,700 yrs...i.e. when you burn FFs there is no C-14 in the added CO2...and Climate Scientists can measure/track the CO2 Isotopes. Do you understand what I'm showing you?
